The document summarizes the key stages in the tire manufacturing process: 1) Rubber compounding involves mixing various types of rubber such as natural rubber and synthetic rubber with chemicals and fillers. 2) Component preparations includes extruding the tread, calendaring fabric, and winding beads. 3) Tire building involves layering the inner liner, beads, fabric, steel belts, and tread to form a green tire. 4) Curing uses heat and pressure to vulcanize the green tire and provide properties like elasticity and durability.
